Tris-(hydroxyamino)triazines: High-affinity chelating tridentate O,N,O-hydroxylamine ligand for the cis-VVO2+ cation

The treatment of the trichloro-1,3,5-triazine with N-methylhydroxylamine hydrochloride results in the replacement of the three chlorine atoms of the triazine ring with the function -N(OH)CH3 yielding the symmetrical tris-(hydroxyamino)triazine ligand H3trihyat. Reaction of the ligand H3trihyat with NaVVO3 in aqueous solution followed by addition of Ph4PCl gave the mononuclear vanadium(v) compound Ph4P[VVO2(Htrihyat)] (1). The structure of compound 1 was determined by X-ray crystallography and indicates that this compound has a distorted square-pyramidal arrangement around vanadium. The ligand Htrihyat2- is bonded to vanadium atom in a tridentate fashion at the triazine ring nitrogen atom and the two deprotonated hydroxylamido oxygen atoms. The high electron density of the triazine ring nitrogen atoms, which results from the resonative contribution of electrons of exocyclic nitrogen atoms, leads to a very strong V-N bond. The cis-[V VO2(Htrihyat)]- species exhibits high hydrolytic stability in aqueous solution over a wide pH range, 2.5-11.5, as was evidenced by potentiometry. The Royal Society of Chemistry 2010.
